To all whom it may concern:

Be it known that I, HERBERT B. SPERRY, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented a new and useful Improvement in a Combined Side-Delivery Hay Rake and Tedder, of which the following is a complete specification. i

This invention relates to an improvemen in side-delivery hay-rakes of the kickingfork type, the object being to produce a machine which can be converted at will into either a side-delivery hay-rake or a tedder, a single implement. with certain modifications thus being made to serve a double function, with the consequent cheapening of the process of curing and handling hay.

Referring to the accompanying drawings, Figure 1 represents a perspective view of a side-delivery hay-rake embodying my im provement. Fig. 2 is a detail of the reversible'gear-clutch, showing a portion of same in side elevation. Fig. 3 is a longitudinal section of a fork-arm, and Fig. 4 is'a detail showing in sideelevation the fork-casting on. the lower end of the fork-arm.

In the drawings the main frame of the rake is designatedby 1, the axle by the numeral 2, and the supporting-wheels on said axle by 3.

The rear end of the frame 1 is supported on the caster-wheel 3. Journaled in the bearings 4 on the cross-bars 1 of the frame 1. is the multiple-crank shaft 5. This crank-shaft is operated by means of a reversible driving connection which is interposed between the supporting-wheels 3 and said. shaft and is constructed as follows: The axle'2 rotates with the wheels 3, and fixed thereto is a large sprocket wheel 6. Journaled in suitable bearings on the rake-frame 1 and extending parallel with the axle 2 is the short c'rossshaft 7, on the outer end of which is fixed the spur-pinion 8 and on the inner end thereof t ie bevel-pinion 9. The last-mentioned bevel-gear meshes with and drives the bevelpinion 10, fixed to the short shaft 11, which extends parallel with the crank-shaft 5. The; shaft 11 journals also in suitable bearings on the main frame and has secured to its other end the sprocket-wheel 12. A small sprocket wheel 13 is fixed to the crank-shaft 5, the chain 14. connecting the two sprocket-wheels. To communicate motion in reverse directions to the pinion 8 on shaft 7, an arm 15 is pivotally mounted at 15 the bracket 16, which is secured to the main frame. Above the pivotal bearing 15 on the lever 15 is ournaled the spur-pinion 17, and meshing thereits pivotal bearing is the pinion 18. These two movable pinions 17 and 18 he in the same plane with the pinion 8, so that when the \lever 15 is rocked in a forward direction the pinion 18 will be thrown in mesh with said pinion 8, and when rocked rearwardly the pinion 17 will be made to mesh therewith, thus driving in a reverse direction, while the lower pinion 18 will run idle. ,Motion is imparted to these pinions 17 and 18 through the sprocket-chain 19, which engages the large sprocket 6 on the axle 2 and a sprocket-wheel 20 on the end of the shaft 17, to which is fixed the pinion 17. Asuitable quadrant, as 21, controls the position of the lever 15, and a chain-tightener 22 adjusts the tension of the chain 19 when the position of the lever is changed.

On the crank-shaft 5 is journaled a series of reversible forks, designated as a whole by a.

hollow fork-arm 23, fixed to a two-part bearing 24, which journals on the wrist of the crank-shaft.- 1n the upper end of the hollow arm 23 is fitted a cored plug 25, adapted to engage the bent end of the fork-controlling rod 26. Near the lower end of the arm 23 is clamped, by means of the bolt 28, the sleeveformed casting 27, the lower end of which is provided with the cam-shaped depression 27 Immediately below the casting 27 and surroundingthe lower end of the fork-arm-23 is the sleeve-formed fork-bracket 29, which is providedat its upper end with a cam propression 27 in the casting 27. These cam services are bilaterally constructed, so that the casting w ill fit together in either of two positions, forward or rearward and one hundred and eighty degrees apart. The forkbracket 29 is provided with the arms 29", which engage thetooth-bar30. The fork tine=,,,or teeth 31 are secured to this bar, as is line with the center of the bar 23. A coilspring33 is placed within said hollow bar 23, secured above by the eyebolt 34, which proi'ects through the cap 25 and connecting beow through the link 35 with the end of the arm 32. wardly-projecting lip 29 of the casting 29,

These forks are comprised, preferably, of aalso the short arm 32, which is arranged in.

with and mounted also on said lever below jection 29', corresponding with the cam de- The arm 32 rests against the down- -to rake the hay forwardly and to one side.

In this position the forks a occupy the positions as shown by the two forks on the left hand side of the machine in Fig. 1. I

To convert the rake into n tedder, the forks a are turned one-half round, or to the )osition indicated by the two forks on the rigl mg moved forwardly to disengage the pinion 17 from the pinion Send to engage pinion 1&4 therewith. The spring 33 will yield sLIlll-' ciently to permit the fork-bucket 29 to be pushed by the cam-surfaces along the iii-r1121 as the fork is being turned halt-round. With the forks in such reversed position and the direetion'of rotation of the erenleslnrft 5 reversed the machine will operate-21s :in ordi-' nary, tedder, except that the hey will. be movecl'soznewhit lrrtemlly as well as real- Wardly. In. such instenees this lateralv movementmight become very desimble,especiill y when drying the hay in windrows, as is frequently done. i
